When you open a TestComplete project suite in network mode, TestExecute creates a folder on the computer where the project suite resides. By default, it is the <Project_Suite>\<[User_Network_Name]> folder. TestExecute stores your personal configuration files to this folder. If the folder cannot be created for some reason (for instance, you have no permission to create this folder on that computer), this message is displayed. To learn more about working with TestComplete project suites and projects in network mode, see TestComplete Documentation.
